How does uniform circular motion differ from uniform linear motion?

When a body moves in a circular path with uniform speed (constant speed).
e.g. A car running at a constant speed 10 km/h and S-t graph is a straight line.

When a body travels an equal distance in equal intervals of time, no matter how
small the intervals may be.Example a stone tied to a thread.

Acceleration of a body moving in a circle is v2/r.

Acceleration of a body moving in a is a = v-u/t
